ANALYZE was observed to race over a preceding in binlog order DML in updating the binlog and slave gtid states. Tagging ANALYZE and other admin class commands in binlog by the fixes of MDEV-17515 left a flaw allowing such race leading to the gtid mode out-of-order error. This is fixed now to observe by ADMIN commands the ordered access to the slave gtid status variables and binlog.
